PATENT OFFICE.

SPECIFICATION forming part of Letters Patent No. 242,717, dated June 7, 1881.

Application filed April 7, 1881.

To all whom it may concern Be it known that I, WILLIAM F. TRIPPEN- SEE, of Clarence, in the county of Erie and State of New York, have invented a new Improvement in Feeding Attachments for Fanning-Mills, of which the followin gis afull, clear, and exact description.

Figure 1 is a side elevation of a fanningmill to which my improvement has been applied. Fig. 2 is a plan view of the same. Fig. 3 is a side elevationof the improvement, parts of the hopper being shown in section.

The object of this invention is to facilitate the cleaning of grain.

The invention consists in constructing a feedin g attachment for fanning-mills of a curved feed-lever, aconnecting-rod hinged to the shoeoperating connecting rod, a double jointed coupling for connecting the rod and lever, a stud to fulcrum the lever, and a feed arm or point attached to the curved lever, whereby the feed-lever will be vibrated to feed the grain by the up-and-down movement of the shoe-operating connecting-rod, as will be hereinafter fully described.

A represents the frame, B the casing, G the I hopper, Dthe fans, and E the connecting-rod for giving motion tothe shoe F, about the construction of which parts there is nothing new.

To the inner surface of one side of the hopper 0 is attached a short stud, G, to the upper end of which is fulcrumed a lever, H. The outer arm of the lever H is curved upward, outward,and downward',and its end is connected by a double-hinged joint or coupling, I, with the upper end of the connecting-bar J, the lower end of which is connected with the connecting-rod E, so that the up-and-dowu movement of the said connecting-rod E will vibrate (ModeL) the lever H. The inner arm of the lever H is curved upward, inward, and downward, and to its end is attached a point or arm, K, which is made with a forked or notched end and serrated edges, as shown in Fig. 3. The inner arm of the lever H is made of such a length and is so curved that the feed-point K will pass through the feed-aperture Lin the hopper-bottom M, and thus feed the grain through the said aperture. The size of the feedaperture L is regulated by a slide, N, placed in rabbeted cleats 0, attached to the lower side of the hopper-bottom M in the ordinary manner.

1 The improvement is especially applicable in cleaning grain that has fine straw mixed with it, and which is liable to clog.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a fan-mill, the combination, with the hopper G and the shoe-operating connectingrod E,of the stud G,the connecting-rod J, the double-jointed coupling I, the curved lever H, and the feeding-arm K, substantially as herein shown and described, whereby the grain will be fed from the hopper automatically, as set forth.

2. A feeding attachment for fan'mills, constructed substantially as herein shown and described, consistiug of the stud G, the connecting-rod J, the double-joihted coupling I, the curved lever H, and the feeding-arm K, to adapt the said attachment to be applied to the hopper and the shoe-operatingconnecting-rod, as set forth.
